The Nokia Lumia series of phones includes the 720, 820, and the 920 handset. The 920 was released in early November 2012 and proved to be an unexpected hit for the struggling phone company.

Earlier this month, Nokia Corporation (NYSE:NOK) (BIT:NOK1V) (HEL:NOK1V)’s management was coerced to admit that they were aware of supply problems with the phone, and were “working with suppliers and operators to work through the situation.”
